To all whom it may concern:

Be it known that I, CHESTER I. HALL, a citizenof the United States, residing at Chicago, in the county of Cook and State of .lllinois, have invented a certain new and useful Improvement in Integrating Electricity-Meters, or" which the following is a full, clear, concise, and exact description,

reference being had tothe accompanying drawings, forming a part of this specifier tion. I

My invention relates t5 integrating electricity meters, and more particularly to apparatus for indicating or recording the time and amount of the maximum consumption of energy.

.Vhen electricity is furnished to con sumers it is'very desirable in order to fix the rate to be charged to each user to know the hour d'f the day when he uses the most electricity, that is to say, whether his maximum consumption occurs during the hours when the greatest demand is made upon the central station, or whether he uses the most energy during oli peak hours, or that part of the day when there is not so great a demand upon the power plant. My invention contemplates mechanism for inaking a record of the hour at which such maximum consumption of energy occurs. 1 v

My invention enables me to know at a glance the hour or other period during which the consumer has used the greatest amountof energy, thus enabling me to fix the rate of charge accordingly.

In conjunction with the apparatus forming the subject of my invention I find it advantageous to use a maximum energy indicating means, the advancement of which is controlled by the integrating meter mecha- I employ suitable power aside fromthat imparting motlon tothe meter in order nism.

to advance the indicating means.

A circuit which is controlled by the indicating means, serves when closed.to set inmeter showing the maximum energy indicating mechanism, and also an hour dial to indicate the time. Fig. 2 is a cross-sectional view taken on a horizontal plane through the center of the meter and partly showing the integrating mechanism directly'above this plane. Fig. 3 is a view of a disk used in connection'with a watt hour meter and the spring which is used as the motive power for advancing the maximum energy indicator. Fig. 4c is a sectional View taken on line tie-fl of F ig. 2. Fig. 5 is a View taken partly in section directly behind the dial of the meter, some of the parts being left out in order to more clearly illustrate the construction. Fig. 6 is a sectional view taken partly through the hour dial and partly in a plane directly above that. Fig. 7 is a side view of a disk andassociated mechanism which is used with the timing element of my invention. Fig. 8 is a face view of the parts shown in Fig. 7. Fig. 9

is an elevation View more or less diagramtened thereto a spiral spring 7, one end of which is secured to a post 8. At one end of the sleeve 6 there is secured a disk 9 which supports a spring pawl 10 which engages a ratchet 11. The sleeve 6 has also secured thereto a cord or flexible cable 12, one end of which is secured to the core 1.? of an electromagnet 14: which may be suitably-mounted. The sleeve 6 is journaled at oneend in the bushing 15 of insulating material and a bushing 16 oi insulating material is held tightly in the plate 1? and forms in connection with the bushing 15 means by which the member 18 is complete y insulated from the'meter :echanism. The mammum indicator 18 1s frictionally mounted by means of a rrlction spring 19, thus permitting the indicator 18 to be advanced over the dial 20 so that it will stay in any position to which it is turned. The outerv end of the sleeve 6 has fastened thereto a driving pointer 21 which is employed to advance the indicator 18 in a manner which will be described.

As the disk 1 of the meter rotates it permits the worm 3 to act as an escapement for the advancement of the gear 4 by means of the torque on the spindle 5 caused by the power spring 7. This is done by the engagement of the spring pawl 10 with the ratchet 11. This has the effect of advanc ing or rotating the driving pointer 21 and through its engagement with the lug 40 on the maximum indicator 18, said indicator is also advanced to indicate the maximum energy consumed during any interval of time,

any other predetermined time.

suchvfor example as every five minutes or In order to secure the proper advancement during every five-minuteperiod, I have employed clock mechanism shown diagrammatically at,22 which has in conjunction therewith a cam 23 for causing a momentary connection between the springs 24 and 25, thereby closing a circuit through the battery 26 and thus, energizing the electromagnet 14. When this magnet is energized at the end of a predetermined period it will serve to rewind the spring 7 to its initial position so that it will be in a condition to again operate the driving pointer 21. In other words, suppose for example, that the driving pointer 21 is returned to its initial position against the stop pin 27 after advancing the indicator 18, which remains at the position to which it may have been driven during the first five-minuteinterval. If during the second five-minute period the driving pointer 21 is advanced farther than it was during the first period, due to a larger consumption ofqenergyduring the second period than during the first, the indicator 18' will be engaged when the driving, pointer reaches the point to which it advanced during the last interval, and the two pointers will move together until the end of the second five-minute period. At that instant the electromagnet 14 operates to return the driving pointer to its initial position, leaving the-indicator 18 at a position in advance of that to which it was drivelduring the first period and where it will indicate the consumption of energy during the second five-minute interval.

During the third five-minute interval the consumption of energy may be less than during the second interval, in which case the driving pointer 21 will not be advanced far enough to engage the indicator 18, with the result that the ndicator will remain in the position to which it was advanced during the second interval. Thus it will be seen that at the end of the month the indicator 18 will be found in a position upon its dial corresponding with the consumption of electrical energy during that period in which the consumption was greatest.

I have found it desirable to know the time when the maximum'amount' of energy consumed occurred and to this end I employ a timing element 28 which is more or less diagrammatically shown and which has operating in conjunction therewith a disk 29 which is adapted to'make one complete revolution in every twentysfo-ur hours. In conjunction with this particular mechanism I have employed means by which the' time of the maximum energ r consumption can be ascertained by looking at the face of the meter, .-which has thereon a dial indicating a. m. and p. in. periods of twelve hours each to correspond with any position of the disk 29. To this end there is rigidly-mount ed upon the spindle 30 an hour hand 31 adapted to pass over the hour dial and on the rearward end of the 'spindle 30 I employ a hand 32 which lies in the same plane with the hour hand 31, the hand 32 being fastened to the spindle 30. A pinion 33 is mounted on the spindle 30-and meshes with .a gear 34 which is suitably mounted upon a shaft indicator 18. Thusit will be seen that when the indicator I8 is being advanced accordingtothe amount of energy'consumed, it closes a circuit through the battery 41, thereby energizing the electromagnet 39 and causing the advancement of the ratchet 37 and through the associated mechanism, the indicators 31 and 32.

It will beiunderstood that the disk 29 rotates constantly under the influence of the clock mechanism 28 and this disk is-provide'd with a pin 42 pivotally mounted thereon, and against one side of which there is a comparatively weak spring 43. When the electromagnet 39 is energized, the gearing ratio being such that the hands are rotated until the hand 32 comes into en age ment with the pin 42 of the disk, this hand 32 will rotate and follow up the pin each time that the circuit is closed through the driving pointer 21 and.indicator 18. The pin, then controls and determines the position of the hour hands-31 and 32. The electromagnet will beenergized just as long as.

105 engagement by means of the lug 40'on the 'llhe energization of the electroinagnet 39 holds the arm 32 a ainst the in 42 in the direction of its motion derived from the clock-work 28, from which it will appear that the pram limits the motion of the arm 32, and thus of the hand 31 which causes "the handll'to. occupya position on the dial corresponding tOlllQ time of energization of the electromagnet 3,9. If, during a certain period, for sample one month, there was a maximum energy consumption at 5 Ocleclgp. m, as shown in dotted lines in Fig.1, the pin 42 on the dish 29 having previously been rotated to a position so that when tl e pointer 32 engages the pin-there will be no further rotation of said arms because this represents the maxim-um demand position. The driving pointer 21 will not engage the lug 40 on the indicator 18 again during that particular month, and consequently the electromagnet will not he again energized. The hands then will he held in this position during the remainder of the month and the hour disk 29 will merely slip by the hand 32 owing to the spring bearing against one side of the pin 42. This condition continues until the meter reader notes the indications of the integrating mechanism as well as the-maximum demand indicator and the hour at. which it occurred when he re-sets the mechanism, namely, ro tates the pointer 18 back to its normal position against the pointer 21 when the same cyclic operation will be carried out as heretot'ore described to indicate the maximum energy consumption for the ensuing month.

"From the foregoing explanation it will be apparent that myarrangement affords means whereby the tiineat which themaximum consumption of eneregy occurs may he ascertained at a glance, thus enabling me to easily establish the rate to be charged a consumer accordingly, j

it is well known that when electricity is fun ished to consumers, a diiierence is made in the rate charged to those who use the energy during off peak hours, and those who use the energy during peak hours, or that period of the day when the demand is greatest upon the power station. I do not wish to limit the scope of my invention to the indication of the hour when such demand occur but I wish it to include means for indicating any particular day or days, or week, and in tact any convenient period during which it is desired to kno\ the maximum demand of energy.

I shall now describe briefly the integrating watt hour me hanism used in conjunction with my invention. To this end there leading to the dials 54c, 55 and 56 are simisary.
